Things to Know – Lock-Down Codes for the Controller-Drive Tray
Use the following table to determine the diagnostic lock-down code definitions on the Seven-Segment Display in
the controller canister. In general, these diagnostics appear only when the controller is in a non-operational state.
The controller can be in a non-operation state as a result of a configuration problem (such as mismatched controller
types) or as a result of a hardware fault. If the amber Controller Service Action Required LED is on, the
non-operational state is the result of a hardware fault.

Diagnostic Code Description
– – The firmware is booting.
.8, 8., or 88 This ESM is being held in reset by another ESM.
AA The ESM A firmware is in the process of booting (the diagnostic
indicator is not yet set).
bb The ESM B firmware is in the process of booting (the diagnostic
indicator is not yet set).
L0 The controller types are mismatched, which result in a suspended
controller state.
L2 A persistent memory error has occurred, which results in a suspended
controller state.
L3 A persistent hardware error has occurred, which results in a suspended
controller state.
L4 A persistent data protection error has occurred, which results in a
suspended controller state.
L5 An auto-code synchronization (ACS) failure has been detected, which
results in a suspended controller state.
L6 An unsupported host interface card has been detected, which results in
a suspended controller state.
L7 A sub-model identifier either has not been set or has been
mismatched, which results in a suspended controller state.
L8 A memory configuration error has occurred, which results in a
suspended controller state.
L9 A link speed mismatch condition has been detected in either the ESM
or the power supply, which results in a suspended controller state.
Lb A host interface card configuration error has been detected, which
results in a suspended controller state.
LC A persistent cache backup configuration error has been detected,
which results in a suspended controller state.
Ld A mixed cache memory DIMMs condition has been detected, which
results in a suspended controller state.
LE Uncertified cache memory DIMM sizes have been detected, which
